Which ones fit your barrel and host?
Check in the BuilderThe Thunder Beast Silencer Summit fires every suppressor entered on the same gun, with the same equipment. Chairman Titanium was measured in 3 tests. Figures can only be compared with others from the same test, so each one links to everything else fired on that gun.

Manufacturer claim
- The Chairman features our proprietary, Nikola Tesla-inspired, Coaxially-vented baffles that route the gasses through the silencer for a longer duration than in a standard baffle configuration, dramatically reducing the overall volume of the weapon when compared to other silencers of similar size.
- Stainless Steel model: 17-4 H900 Stainless Steel baffles, mount and cap with a Grade 9 Titanium tube, 16oz without mount. Titanium model: Grade 5 6Al4V baffles, mount and cap with a Grade 9 Titanium tube and a 17-4 H900 blast baffle, 11.5oz without mount.
- The BOSS Chairman is our unrivaled .30cal silencer option, offering the best sound suppression for your high-velocity, 7.62mm/308 long rifles, but also gets your 300 Blackout rigs scary close to movie quiet.
- For AR10/15s or any other gas impingement firearms, we recommend selecting the vented cap option for dramatically reduced back pressure and gas exposure. Bolt guns should use the standard end cap option.
